Win32_NetworkAdapterConfiguration class

The Win32_NetworkAdapterConfiguration WMI class represents the attributes and behaviors of a network adapter. This class includes extra properties and methods that support the management of the TCP/IP protocol that are independent from the network adapter.

The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties. Properties are listed in alphabetic order, not MOF order.

Properties

The Win32_NetworkAdapterConfiguration class has these properties.

ArpAlwaysSourceRoute

Data type: boolean

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|ArpAlwaysSourceRoute")

If TRUE, TCP/IP transmits Address Resolution Protocol (ARP) queries with source routing enabled on Token Ring networks. By default (FALSE), ARP first queries without source routing, and then retries with source routing enabled if no reply is received. Source routing allows the routing of network packets across different types of networks.

ArpUseEtherSNAP

Data type: boolean

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|ArpUseEtherSNAP")

If TRUE, Ethernet packets follow the IEEE 802.3 Sub-Network Access Protocol (SNAP) encoding. Setting this parameter to 1 forces TCP/IP to transmit Ethernet packets by using 802.3 SNAP encoding. By default (FALSE), the stack transmits packets in DIX Ethernet format.

Caption

Data type: string

Access type: Read-only

Qualifiers: MaxLen (64)

Short textual description of the current object.

This property is inherited from CIM_Setting.

DatabasePath

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|DatabasePath")

Valid Windows file path to standard Internet database files (HOSTS, LMHOSTS, NETWORKS, and PROTOCOLS). The file path is used by the Windows Sockets interface.

DeadGWDetectEnabled

Data type: boolean

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|EnableDeadGWDetect")

If TRUE, dead gateway detection occurs. With this feature enabled, Transmission Control Protocol (TCP) asks Internet Protocol (IP) to change to a backup gateway if it retransmits a segment several times without receiving a response.

DefaultIPGateway

Data type: string array

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|System\\CurrentControlSet\\Services|Parameters|DefaultGateway")

Array of IP addresses of default gateways that the computer system uses.

Example: "192.168.12.1 192.168.46.1"

DefaultTOS

Data type: uint8

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|DefaultTOS")

Default Type Of Service (TOS) value set in the header of outgoing IP packets. Request for Comments (RFC) 791 defines the values. Default: 0 (zero), Valid Range: 0 - 255.

DefaultTTL

Data type: uint8

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|DefaultTTL")

Default Time To Live (TTL) value set in the header of outgoing IP packets. The TTL specifies the number of routers an IP packet can pass through to reach its destination before being discarded. Each router decrements by one the TTL count of a packet as it passes through and discards the packets—if the TTL is 0 (zero). Default: 32, Valid Range: 1 - 255.

Description

Data type: string

Access type: Read-only

Textual description of the current object.

This property is inherited from CIM_Setting.

Organization name followed by a period and an extension that indicates the type of organization, such as "microsoft.com". The name can be any combination of the letters A through Z, the numerals 0 through 9, and the hyphen (-), plus the period (.) character used as a separator.

Example: "microsoft.com"

DNSDomainSuffixSearchOrder

Data type: string array

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|SearchList")

Array of DNS domain suffixes to be appended to the end of host names during name resolution. When attempting to resolve a fully qualified domain name (FQDN) from a host-only name, the system will first append the local domain name. If this is not successful, the system will use the domain suffix list to create additional FQDNs in the order listed and query DNS servers for each.

Example: "samples.microsoft.com example.microsoft.com"

DNSEnabledForWINSResolution

Data type: boolean

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|EnableDNS")

If TRUE, the Domain Name System (DNS) is enabled for name resolution over Windows Internet Naming Service (WINS) resolution. If the name cannot be resolved using DNS, the name request is forwarded to WINS for resolution.

DNSHostName

Data type: string

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|Hostname")

Host name used to identify the local computer for authentication by some utilities. Other TCP/IP-based utilities can use this value to acquire the name of the local computer. Host names are stored on DNS servers in a table that maps names to IP addresses for use by DNS. The name can be any combination of the letters A through Z, the numerals 0 through 9, and the hyphen (-), plus the period (.) character used as a separator. By default, this value is the Microsoft networking computer name, but the network administrator can assign another host name without affecting the computer name.

Example: "corpdns"

DNSServerSearchOrder

Data type: string array

The domain name of this connection is either set using the SetDNSDomain() method or assigned by DSCP. The registered name is the host name of the computer with the domain name appended.

ForwardBufferMemory

Data type: uint32

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|ForwardBufferMemory"), Units ("bytes")

Memory allocated by IP to store packet data in the router packet queue. When this buffer space is filled, the router begins discarding packets at random from its queue. Packet queue data buffers are 256 bytes in length, so the value of this parameter should be a multiple of 256. Multiple buffers are chained together for larger packets. The IP header for a packet is stored separately. This parameter is ignored and no buffers are allocated if the IP router is not enabled. The buffer size can range from the network MTU to a value smaller than 0xFFFFFFFF. Default: 74240 (fifty 1480-byte packets, rounded to a multiple of 256).

FullDNSRegistrationEnabled

Data type: boolean

Qualifiers: MappingStrings ("Win32Registry|System\\CurrentControlSet\\Services|Parameters\\Tcpip")

If TRUE, TCP/IP is bound and enabled on this network adapter.

IPFilterSecurityEnabled

Data type: boolean

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|IPFilterSecurityEnabled")

If TRUE, IP port security is enabled globally across all IP-bound network adapters and the security values associated with individual network adapters are in effect. This property is used in conjunction with IPSecPermitTCPPorts, IPSecPermitUDPPorts, and IPSecPermitIPProtocols. If FALSE, IP filter security is disabled across all network adapters and allows all port and protocol traffic to flow unfiltered.

IPPortSecurityEnabled

Data type: boolean

Access type: Read-only

Qualifiers: DEPRECATED, MappingStrings ("WMI|Win32_NetworkAdapterConfiguration|IPFilterSecurityEnabled")

IPSecPermitIPProtocols

Data type: string array

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|RawIPAllowedProtocols")

Array of the protocols permitted to run over the IP. The list of protocols is defined using the EnableIPSec method. The list will either be empty or contain numeric values.

IPUseZeroBroadcast

Data type: boolean

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|UseZeroBroadcast")

If TRUE, IP zeros-broadcasts are used (0.0.0.0), and the system uses ones-broadcasts (255.255.255.255). Computer systems generally use ones-broadcasts, but those derived from BSD implementations use zeros-broadcasts. Systems that do not use that same broadcasts will not interoperate on the same network. The default is FALSE.

KeepAliveInterval

Data type: uint32

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|KeepAliveInterval"), Units ("milliseconds")

Interval separating Keep Alive Retransmissions until a response is received. After a response is received, the delay until the next Keep Alive Transmission is again controlled by the value of KeepAliveTime. The connection will be aborted after the number of retransmissions specified by TcpMaxDataRetransmissions have gone unanswered. Default: 1000, Valid Range: 1 - 0xFFFFFFFF.

KeepAliveTime

Data type: uint32

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|KeepAliveInterval"), Units ("milliseconds")

The KeepAliveTime property indicates how often the TCP attempts to verify that an idle connection is still intact by sending a Keep Alive Packet. A remote system that is reachable will acknowledge the keep alive transmission. Keep Alive packets are not sent by default. This feature may be enabled in a connection by an application. Default: 7,200,000 (two hours).

MACAddress

Data type: string

Access type: Read-only

Qualifiers: MappingStrings ("Win32API|Device Input and Output Functions|DeviceIoControl")

Media Access Control (MAC) address of the network adapter. A MAC address is assigned by the manufacturer to uniquely identify the network adapter.

Example: "00:80:C7:8F:6C:96"

MTU

Data type: uint32

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|MTU"), Units ("bytes")

Overrides the default Maximum Transmission Unit (MTU) for a network interface. The MTU is the maximum packet size (including the transport header) that the transport will transmit over the underlying network. The IP datagram can span multiple packets. The range of this value spans the minimum packet size (68) to the MTU supported by the underlying network.

NumForwardPackets

Data type: uint32

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|NumForwardPackets")

Number of IP packet headers allocated for the router packet queue. When all headers are in use, the router will begin to discard packets from the queue at random. This value should be at least as large as the ForwardBufferMemory value divided by the maximum IP data size of the networks connected to the router. It should be no larger than the ForwardBufferMemory value divided by 256, since at least 256 bytes of forward buffer memory are used for each packet. The optimal number of forward packets for a given ForwardBufferMemory size depends on the type of traffic on the network. It will be somewhere between these two values. If the router is not enabled, this parameter is ignored and no headers are allocated. Default: 50, Valid Range: 1 - 0xFFFFFFFE.

PMTUBHDetectEnabled

Data type: boolean

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|EnablePMTUBHDetect")

If TRUE, detection of black hole routers occurs while TCP discovers the path of the Maximum Transmission Unit. A black hole router does not return ICMP Destination Unreachable messages when it needs to fragment an IP datagram with the Don't Fragment bit set. TCP depends on receiving these messages to perform Path MTU Discovery. With this feature enabled, TCP will try to send segments without the Don't Fragment bit set if several retransmissions of a segment go unacknowledged. If the segment is acknowledged as a result, the MSS will be decreased and the Don't Fragment bit will be set in future packets on the connection. Enabling black hole detection increases the maximum number of retransmissions performed for a given segment. The default value of this property is FALSE.

PMTUDiscoveryEnabled

Data type: boolean

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|EnablePMTUDiscovery")

If TRUE, the Maximum Transmission Unit (MTU) path is discovered over the path to a remote host. By discovering the MTU path and limiting TCP segments to this size, TCP can eliminate fragmentation at routers along the path that connect networks with different MTUs. Fragmentation adversely affects TCP throughput and network congestion. Setting this parameter to FALSE causes an MTU of 576 bytes to be used for all connections that are not to machines on the local subnet. The default is TRUE.

ServiceName

Data type: string

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|Software\\Microsoft\\Windows NT\\CurrentVersion\\NetworkCards|ServiceName")

Service name of the network adapter. This name is usually shorter than the full product name.

Example: "Elnkii"

SettingID

Data type: string

Access type: Read-only

Qualifiers: MaxLen (256)

Identifier by which the current object is known.

This property is inherited from CIM_Setting.

TcpipNetbiosOptions

Data type: uint32

Access type: Read-only

EnableNetbiosViaDhcp (0)

EnableNetbios (1)

DisableNetbios (2)

TcpMaxConnectRetransmissions

Data type: uint32

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|TcpMaxConnectRetransmissions")

Number of times TCP attempts to retransmit a Connect Request before terminating the connection. The initial retransmission timeout is 3 seconds. The retransmission timeout doubles for each attempt. Default: 3, Valid Range: 0 - 0xFFFFFFFF.

TcpMaxDataRetransmissions

Data type: uint32

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|TcpMaxDataRetransmissions")

Number of times TCP retransmits an individual data segment (nonconnect segment) before terminating the connection. The retransmission timeout doubles with each successive retransmission on a connection. Default: 5, Valid Range: 0 - 0xFFFFFFFF.

TcpNumConnections

Data type: uint32

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|TcpNumConnections")

Maximum number of connections that TCP can have open simultaneously. Default: 0xFFFFFE, Valid Range: 0 - 0xFFFFFE.

TcpUseRFC1122UrgentPointer

Data type: boolean

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|TcpUseRFC1122UrgentPointer")

If TRUE, TCP uses the RFC 1122 specification for urgent data. If FALSE (default), TCP uses the mode used by Berkeley Software Design (BSD) derived systems. The two mechanisms interpret the urgent pointer differently and are not interoperable. The default value is FALSE.

TcpWindowSize

Data type: uint16

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|TcpWindowSize"), Units ("bytes")

Maximum TCP Receive Window size offered by the system. The Receive Window specifies the number of bytes a sender may transmit without receiving an acknowledgment. In general, larger receiving windows will improve performance over high-delay and high-bandwidth networks. For efficiency, the receiving window should be an even multiple of the TCP Maximum Segment Size (MSS). Default: Four times the maximum TCP data size or an even multiple of TCP data size rounded up to the nearest multiple of 8192. Ethernet networks default to 8760. Valid range: 0 - 65535.

Note

Windows Vista: This property accesses the "CurrentControlSet\\Services\\Tcpip\\Parameters|TcpWindowSize" registry entry, which is not used in the current implementation of the operating system.

 

WINSEnableLMHostsLookup

Data type: boolean

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|EnableLMHOSTS")

IP address for the primary WINS server.

WINSScopeID

Data type: string

Access type: Read-only

Qualifiers: MappingStrings ("Win32Registry|SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters|ScopeID")

Value appended to the end of the NetBIOS name that isolates a group of computer systems communicating with only each other. It is used for all NetBIOS transactions over TCP/IP communications from that computer system. Computers configured with identical scope identifiers are able to communicate with this computer. TCP/IP clients with different scope identifiers disregard packets from computers with this scope identifier. Valid only when the EnableWINS method executes successfully.

WINSSecondaryServer

Data type: string

Access type: Read-only

Qualifiers: MappingStrings ("Win32API|Device Input and Output Functions|DeviceIoControl")

IP address for the secondary WINS server.

Remarks

The Win32_NetworkAdapterConfiguration class is derived from CIM_Setting.

Examples

The following PowerShell code retrieves the configuration settings for the Microsoft ISTAP Adapter.

$IstapAdapterConfig = Get-WmiObject Win32_NetworkAdapterConfiguration | Where-Object {$_.Description -eq "Microsoft ISATAP Adapter"}
$IstapAdapterConfig

The following C# sample retrieves the description and index number of all network adapter configuration instances. Note that this C# sample uses the Microsoft.Management.Infrastructure namespace, which generally scales more efficiently than the System.Management namespace WMI classes.

using Microsoft.Management.Infrastructure;
...
static void QueryInstanceFunc()
{
   CimSession session = CimSession.Create("localHost");
   IEnumerable<CimInstance> queryInstance = session.QueryInstances(@"root\cimv2", "WQL", "SELECT * FROM Win32_NetworkAdapterConfiguration");

   foreach (CimInstance cimObj in queryInstance)
   {
      Console.WriteLine(cimObj.CimInstanceProperties["Index"].ToString());
      Console.WriteLine(cimObj.CimInstanceProperties["Description"].ToString());
      Console.WriteLine();
   }

Console.ReadLine();
}

The following C# sample retrieves the description and index number of all network adapter configuration instances. Note that this C# sample uses the original System.Management namespace, which has been superceded by Microsoft.Management.Infrastructure.

using System.Management;
...
static void oldSchoolQueryInstanceFunc()
{

   ObjectQuery query = new ObjectQuery("SELECT * FROM Win32_NetworkAdapterConfiguration");
   ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);

   ManagementObjectCollection queryCollection = searcher.Get();
   foreach (ManagementObject m in queryCollection)
   {
      Console.WriteLine("Index : {0}", m["Index"]);
      Console.WriteLine("Description : {0}", m["Description"]);
      Console.WriteLine();
   }
   Console.ReadLine();
}

The following example retrieves information from the Win32_NetworkAdapterConfiguration class.
